| Abstract: | Epinephelus is among the most important fish genera in the Southeast Asian Pacific coastal systems. In Chinese coast, the orange‐spotted grouper Epinephelus coioides is one of the most significant species based on culture volume, and it is consumed all over the world. Very little information exists on this species’ parasitofauna. Composition and temporal variation in the community structure of the gill monogeneans on wild versus cultured E. coioides from Daya Bay (23°25′N, 117°2′E), South China Sea were determined using seasonal samples taken between April 2008 and January 2009. Eight species of monogeneans of three families and four genera on the gills of E. coioides were found: Neobenedenia melleni, Haliotrema cromileptis, Diplectanum grouperi, Pseudorhabdosynochus justinei, P. lantauensis, P. coioidesis, P. serrani and P. shenzhenensis. Eight of the monogenean species exhibited seasonal variation in their infection dynamics associated with environmental changes during seasons. The variations in the infection dynamics generated changes in the community structure during the sampling periods. Moreover, in the three different host living environments (wild, monocultured and polycultured), the monogenean communities exhibited the different seasonal patterns. |
